Coleus Festive Dance may be grown from seed sown early indoors and transplanted outside after frost, or from potted plants.
Sowing Seed Indoors:
- Coleus Festive Dance Seeds Sow indoors 6-8 weeks before last frost using a seed starting kit.
- Sow sees shallowly lightly covered with fine seed starting soil.
- Keep the soil moist at 65-85 degrees. Coleus can benefit with bottom heat.
- Seedlings emerge in 12-21 days
- As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
- Thin to one seedling per cell when they have two sets of leaves.
- Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
- Transplant hardened-off seedlings to the garden after the frost.
- Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.
